Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction drawing or the like using a CAD system or the like, and more particularly to a method and apparatus for forming a skeleton figure such as a pillar, a wall or a beam.

[0002]

2. Description of the Related Art Conventionally, by drawing (tracing) a drawing set on a digitizer, the drawing in the drawing is CA.
In the case of making a D drawing, the commands of basic columns, basic beams, and basic walls are used for basic frame figures such as basic columns, basic beams, and basic walls, respectively. The basic column command is a command that can create a column based on the intersection of the standard core and the basic beam command. Among the two intersections of the standard core, the line connecting these intersections is a horizontal line or a vertical line. This is a command that can create a beam only between two intersecting points, and the basic wall command is only between two intersecting points where the line connecting these intersecting points is a horizontal line or a vertical line among two intersecting points of the standard core. A command that can create a wall.

FIG. 17 shows processing corresponding to a conventional basic pillar (square pillar) command. First, in step S101, the operator, for example, with respect to a window 180 as shown in FIG.
Enter parameters such as the directional offset value and the upper and lower wall height limits. Next, the operator designates a point P indicating the arrangement position of the pillar to be created (step S102) (the point P is the intersection of the standard cores L1 and L2). Next, the CPU executes step S1.
It is checked whether the offset value input in 01 is valid. If it is valid (YES in step S103), the operator is prompted to specify the offset direction. FIG. 19 shows a point P indicating the arrangement position of the column designated in step S102 and a point OFF indicating the offset direction designated in step S104. When the instruction of the offset direction is completed, the CPU sets the designated point P as the reference position and creates a basic column based on the point OFF indicating the offset direction (step S105). FIG. 20 shows step S10.
The basic pillar H created in 5 is shown.

[0004]

In the above-described creation method of FIG. 17, the offset value is keyboard input from the drawing (when not specified in the drawing, the offset value is measured on the scale and then keyboard input). There was a problem that input was troublesome.

FIG. 2 is a flowchart showing an operation example of the embodiment of FIG. 1, that is, a basic pillar (prism) forming operation.
The operation of the embodiment shown in FIG. 1 will be described below with reference to FIG. First, the operator inputs a basic pillar (square pillar) creation command from the keyboard 2. In response to this, the CPU 7 sets the basic pillar creation flag in the storage area 9b of the RAM 9. Then, in step S1, the operator traces the pillar of the set drawing and moves to the point P1.
And P2 are instructed by the digitizer 3D to instruct the arrangement position of the column (see FIG. 3. Note that in FIG. 3, line segments L1 and L2 indicate the core according to the reference).
As a result, the CPU 7 causes the designated points P1 and P2.
Are stored in the designated point storage area 9d of the RAM 9.

Next, the CPU 7 recognizes a reference position S which is an intersection of the reference line L1 and the reference line L2. Figure 4
As shown in FIG.
The reference position S, which is the intersection with 2, is the designated points P1 and P2.
CP within the rectangular area HA specified by
U7 can recognize the reference position S (N in step S2).
O). Then, the CPU 7 stores the recognized coordinates of the reference position S in a predetermined area of the RAM 9. The CPU 7 is shown in FIG.
As shown in FIG.
The reference position S, which is the intersection with 2, is the designated points P1 and P2.
If it does not exist in the rectangular area HA specified by
Alternatively, as shown in FIG. 6, when there are a plurality of reference positions within the rectangular area HA specified by the designated points P1 and P2 (in the example of FIG. 6, the reference cores L1 and L3 and the reference cores L3 and L3). There are two reference positions S1 and S2 which are the intersections with the core L2), and the reference position cannot be recognized (YES in step S2). When the reference position cannot be recognized, the CPU 7 displays a message to that effect on the display 5 and prompts the operator to specify the reference position (step S).
3). Then, the CPU 7 stores the coordinates of the designated reference position in a predetermined area of the RAM 9. Next, CPU7
Is the point P1 stored in the designated point storage area 9e of the RAM 9.
Based on the coordinates of P2 and P2 and the coordinates indicating the reference position S stored in a predetermined area of the RAM 9, the basic pillar H is created (step S4) (see FIG. 4).

FIG. 7 mainly shows a specific processing example of automatic reference position recognition in the basic pillar creating operation of the embodiment shown in FIG. Here, it is assumed that the operator has set the parameters for the basic pillars in advance. To explain this parameter setting process, first, the operator
A basic pillar setting command is input via the keyboard 2. In response to this, the CPU 7 causes the area 9a of the RAM 9 to
Then, the basic pillar setting flag is set, the graphic creation device is set to the basic pillar setting mode, and the pillar setting window 80 shown in FIG. 8 is displayed on the display 5. The operator inputs the upper limit value and the lower limit value of the height of the wall into the predetermined area of the column setting window 80 from the keyboard 2 (step S4).
1). In response to this, the CPU 7 stores the input upper limit value and lower limit value of the height of the column in the parameter storage area 9d of the RAM 9 (step S42).

Returning to the explanation of the basic pillar creating process, first, C
The PU 7 reads the upper limit value and the lower limit value of the height of the basic column stored in the parameter storage area 9d of the RAM 9 (step S43). Next, the operator indicates the positions of the pillars by pointing the points P1 and P2 by the digitizer 3D while tracing the pillars in the set drawing (see FIG. 9. In FIG. 9, (x1 , Y
1) indicates the coordinates of the designated point P1, and (x2, y2) is
The coordinates of the designated point P2 are shown. ) (Steps S44 and S
45). The processing of steps S44 and S45 of FIG. 7 is the same as the processing of step S1 of FIG.
7 stores the coordinates of the designated points P1 and P2 in the RAM 9
Is stored in the designated point storage area 9e.

Next, the CPU 7 causes the designated points P1 and P2.
The representative point of the pillar, that is, the reference position S, is searched in the rectangular area HA specified by (step S46). The number of representative points of the pillars in the rectangular area HA, that is, the number of reference positions S is 1
If the pillars are individual (YES in step S47) and the pillars are not arranged yet (YES in step S48), CP
U7 obtains the vertical width and horizontal width of the pillar (step S4).
9). The CPU 7 determines the coordinates (x1, y1) and (x of the designated points P1 and P2 from the designated point storage area 9e of the RAM 9 by way of example.
2, Y2) is read and the following calculation is performed to obtain the vertical width and the horizontal width of the column. Vertical width = | x2-x1 | Horizontal width = | y2-y1 |

Next, the CPU 7 obtains the column offset value (step S50). The method of obtaining the offset value will be described with reference to FIG.
The coordinates (x1, y1) and (x2, Y2) of the designated points P1 and P2 are read from the designated point storage area 9e of 9,
The following calculation is performed to find the coordinates (x _c , y _c ) of the center point C of the column. x _c = (x1 + x2) / 2 y _c = (y1 + y2) / 2 Next, the CPU 7 reads the representative point of the pillar, that is, the coordinates (x _s , y _s ) of the reference position S from a predetermined area of the RAM 9,
The offset value (Δx, Δy) of the column is obtained by performing the following calculation and stored in a predetermined area of the RAM 9. Δx = | x _c −x _s | Δy = | y _c −y _s | Then, the CPU 7 causes the RAM 9 to store the parameter storage area 9
A pillar is created based on the upper and lower limit values of the height of the pillar stored in d, and the offset value (Δx, Δy) of the pillar stored in a predetermined area of the RAM 9 (step S
51). Further, the CPU 7 finally displays the graphic, that is, the pillar, stored in the video RAM area 9e of the RAM 9 on the display 5, and when the operator inputs a print command via the keyboard 2, causes the plotter 6 to print.

Returning to step S47, when the number of the representative points of the pillars in the rectangular area HA, that is, the number of the reference positions S is two or more (NO in step S47), the CPU 7 starts the figure creating apparatus of FIG. Sometimes hard disk 1 to RAM 9
The invalid pillar is designated by referring to the graphic ID table, the graphic information table and the constituent element table loaded in step S52.

Since it is easier to understand the process of instructing the invalid pillar by using a concrete example, a prism will be described as an example. The prism is made up of two points, point 1 and point 2 and four lines, line 1, line 2, line 3 and line 4, as shown in FIG. Point 1 is the representative point and point 2 is the center point. These points and lines, and the prisms that make them up (ie,
As shown in FIG. 12, a graphic ID number is assigned to each group), and the graphic ID table 9g stores a graphic ID number for each graphic ID number, that is, for each component. A pointer, a pointer to the constituent element table 9i, a graphic type (for example, distinction between points, line segments, and groups), a pointer to the graphic information table 9h, and the like are stored. Further, a pointer indicating the storage area of the pointer to the first component stored in the graphic information table 9h is stored in the rectangular column of the graphic ID table 9g, that is, the area corresponding to the group 1.

In addition to the pointers of the above-mentioned first constituent elements, the graphic information table 9h has, as shown in FIG. 12, for points 1 and 2 the coordinates of these points in the corresponding areas. For line segment 1 and line segment 2, the coordinates of the two end points of these line segments are stored in the areas corresponding to these. As shown in FIG. 12, the component table 9i stores the relationship between the components of the group (in the example of FIG. 11, the prismatic components, that is, the relationship between two points and four line segments). For each component, the graphic ID of the component, the pointer to the previous component, the pointer to the subsequent component, and the parent graphic ID are stored.

First, the CPU 7 first sends the figure ID table 9g.
The area of group 1 is read, and the "first component pointer" is read from the graphic information table 9h using the read information. Next, the CPU 7 reads the area in the component table 9i indicated by the "pointer of the first component". As a result, the figure ID at the point 1 is read out, and it means that there is a component.

Next, the CPU 7 causes the constituent element table 9 in the storage information of the graphic ID table 9g read out earlier.
The pointer to i is used to get the pointer of the next component from the component table 9i. As a result, the figure ID of the point 2 is read from the constituent element table 9i. However, in the case of an invalid pillar, since the graphic of points 2 to 4 does not exist, the graphic ID of point 2 is not stored in the component table 9i. Therefore, the CPU 7 determines that this group, that is, the prism, is an invalid pillar.

Even when the number of representative points in the rectangular area HA is one (YES in step S47), the CPU 7 determines that the pillar is already arranged (N in step S48).
In O), the operator is requested to instruct the invalid pillar (step S52).

FIG. 13 is a flowchart mainly showing an example of a pillar representative point creating operation in the basic core creating operation of the embodiment shown in FIG. First, the operator selects points P11 and P

It is stored in the designated point storage area 9e of M9.

Next, the CPU 7 causes the designated points P11 and P12.
A line segment L12 connecting between and is created, and the intersections S11 and S12 of this line segment L12 and the already-arranged reference line cores L11 and L13 are searched (step S63) (FIG. 1).
4), a pillar representative point attribute is added to these intersections S11 and S12 (step S64). As described with reference to FIG. 7, one basic pillar is arranged for each pillar representative point. This is managed by the parameter of the column type inside the column attribute, and when the column type is invalid, the column type is set to “invalid”. For example, when the pillar is a prism or a cylinder, the pillar type is "square" or "cylinder".
Is set.

In the above embodiment, the CPU 7 and the ROM 8 recognize the reference position from at least two points to be processed and create the figure at the recognized reference position. However, instead of the CPU and the ROM, , Dedicated hardware may be provided. Further, a recognition means for recognizing the reference position from at least two points to be processed and a graphic creation means for creating a graphic at the recognized reference position may be separately provided.

Further, although the above-mentioned embodiments relate to the production of prisms, the present invention can be applied not only to prisms but also to cylinders, and it is not limited to pillars, and various skeletons such as walls and beams can be used. Applicable to creation. FIG. 15 shows an example of a designated point in the case of a cylinder (in this case, it is necessary to designate three or more points), and FIG. 16 shows an example of a designated point in the case of a wall. In addition,
15 and 16, lines L1, L2 and L3
